And every other third-party Django application on the planet. I can't see that it's feasible to make this kind of change (adding max_length) to TextField now. That ties everybody else to Firebird's restriction, which isn't fair. This might be one of those cases where you just need to document the restriction in your backend's documentation and say that TextFields for firebird will automatically have a maximum length of X for whatever value "X" is. > 2.

Could you clarify this a bit more, please. I don't understand what you're asking. Why aren't the normal field length validations enough (except for TextField)? Is it a matter of making sure somebody doesn't try to create a model that has fields which are too large in the first place (which could be done by hooking into the class_prepared signal and doing a quick pass over the fields at that point -- which is when the model is imported -- to check for inconsistencies). Imposing arbitrary restrictions on lengths isn't something that's built in. Maybe it's needed, maybe not... I have no real opinion on that at the moment. Need to understand the problem better. > 3.

It's on the list, but not yet implemented.
